Summary: | Brinjal (Solanum melongena L.) is one of the commonly consumed vegetable in many countries including Pakistan. And attack by sucking and chewing insect pests likewise, Jassid, aphid, whitefly, shoot and fruit borers, cause significant losses in yield production. Therefore a research trail was conducted to evaluate effect of plant extracts against sucking and chewing insect pests and their associated natural enemies in brinjal crop under field conditions. For this four different plant extracts (Neem seed, Garlic, Eucalyptus and Tobacco) were used to evaluate their efficacy. Two sprays were applied at fifteen intervals and data was recorded before and after 24 hours and 72 hours after spray. In present results, we observed that all plant extracts significantly reduced insect pest population as compared with control groups, while among plant extracts the neem seed and garlic extract were observed more lethal to jassids, aphids and on white flies respectively, as compared to eucalyptus and tobacco extract. Similarly, a minimum damage % of fruit borer was also observed in neem seed and garlic extract as compared to tobacco and eucalyptus. However, no adverse effects were observed on natural enemies. |
